After a demo for Detox hit the Internet earlier this month, there was rampant speculation that Ludacris was ghostwriting for Dr. Dre. Luda goes on the record to address the rumors.

“It was for Dre. I wrote it for Dre,” Luda tells Rap-Up.com of the leaked song “O.G.’s Theme,” which finds him rapping, “Ain’t no ni**a better than Doc Dre, I’m a 20-year veteran.”

Ludacris confirms that the reference track was intended for the West Coast rap pioneer’s highly-anticipated new album, but he’s not sure what will become of it now. “It was supposed to be for Detox, but I don’t know since it got leaked. I don’t know if it’s gonna get used.”

He admits to writing more than one record for Detox, tentatively scheduled for release by the end of the year. “I wrote a couple records and that was one of them.”
